Specification of Letters Patent.

To all whom it may concern:

Be it known that I, JOHN HERBERT HEW- ITT, of 7 Priory road, Edgbaston, Birmingham, England, engineer, have invented certain new and useful Improvements in and Relating to Loose-Leaf Books, Temporary Binders, Files, and the Like, of which the following is a specification.

This invention relates to loose leaf books, temporary binders, files and the like of the type having telescopic filing members adapted to be locked against relative movement whereby the papers 'or the like are clamped in position and has for its object to provide an improved construction thereof.

In a loose leaf book, temporary binder, file or the like made in accordance with this invention the telescopic filing members are adapted to be held together in any desired position by the expression of one of the members so as to grip the other member by frictional contact.

Referring now to the accompanying drawings Figure 1 is a face view partly in section of one form of device constructed in accordance with this invention; Fig. 2 is a view of Fig. 1 looking in the direction of the arrow X with the cover removed; Fig. 3 is a part similar view of Fig. 2 showing the locking device in the unlocked position; Fig. 4L is a section on line A-A of Fig. 2; Fig. 5 is a part sectional elevation similar to Fig. 1 showing a modified form of this invention; Fig. 6 is a side elevation with cover removed.

a; a and Z) 6 are main and c c and cl d are auxiliary telescopic filing members secured to plates 6 f as usual. Each of the inner filing members a a, is hollow and disposed therein and passing through the plates 6 is a rod 9 having a conical head it. The free end of each of the members a a is split as at y and is preferably cone-shaped internally. The upper ends of the rods 9 g are provided .with any known means for imparting longitudinal motion to said rods so that when the conical heads h h are forced into the split ends of the filing members a a said members are expressed and grip the corresponding outer members I) b by frictional contact thereby holding said telescopic members against relative movement. For instance each of the rods may have a head 70 with an inclined face no adapted to be engaged by a correspondingly inclined cam 11. slidden along the plate 6. The cams a may receive their motion through toggle links 0 0 a a to disengage the conical heads h 72, from the members a a when the heads 70 7c of the rods 9 g are released, and s s are springs coiled within the filing members d d to force apart the plates 6 and f when the frictional contact between the members a a and Z) Z) is released.

2, t are covers suitably secured to the plates 6 and f.

It is not strictly necessary to use the coiled springs 1" since the split ends of the inner tubular members have suficient spring in themselves to force out the cones when the cams, are released.

Inthe modified form shown in Figs. 5 and 6 the rod 9 is secured to the cover (6 and the tubular filing member a is free to slide on said rod. In this form any attempt to pull apart the plates 6 and 7 further expresses the member a and increases its frictional grip on the member h. To release the grip the member a is provided with a head a having inclined faces adapted to be engaged by an inclined surface 4) on a member to sliding on the plate 6, so that when the member to is slid the inclined surface 1; engaging under the head a, lifts the split end of the filing member a away from the conical head it against the action of a spring at.

hat I claim and desire to secure by Letters Patent is y 1. A loose leaf book, temporary binder, file or the like having members moving relatively, one of which is adapted to frictionally clutch the other, a rod adapted to move axially and non-rotatively to operate said clutching member, and a cam for displacing said rod non-rotatively to frictionally clutch said members.

2. A loose leaf book, temporary binder, file or the like having members moving relatively, one of which is adapted to frictionally clutch the other, a rod adapted to move axially and non-rotatively to operate said clutching member, a cam for displacing said rod non-rotatively to frictionally clutch said members, and a sliding member adapted to operate said cam.

3. A loose leaf book, temporary binder,

, simultaneously operating said cams.

l. A loose leaf book, temporary binder, file or the like having a plurality of pairs of members, the members of each pair moving relatively and one being adapted to frictionally clutch the other, a plurality of rods adapted to move axially and non-rotatively to operate said clutching members, cams for displacing said rods non-rotatively to frictionally clutch said members and a single means for operating said cams.

5. A loose leaf book, temporary binder, file or the like having a plurality of pairs of members, the members of each pair moving relatively and one being adapted to frictionally clutch the other, a plurality of rods adapted to move axially and non-rotatively to operate said clutching members, cams for displacing said rods non-rotatively to frictionally clutch said members, sliding members adapted to operate said cams and a single means for operating said sliding members.

6. A loose leaf book, temporary binder, file or the like comprising two plates, hollow inner main filing members mounted on one plate and hollow outer main filing members mounted on the other plate, split ends to said inner filing members, a rod disposed in each of said inner filing members and adapted to be slid therein, a conical head to each of said rods, cams for forcing said conical heads into the split ends of the inner filing members, and means for simultaneously operating said cams, substantially as set forth.

7. A loose leaf book, temporary binder, file or the like comprising two plates, hollow inner main filing members mounted on one plate and hollow outer main filing members mounted on the other plate, split ends to said inner filing members, a rod disposed in each of said inner filing members and adapted to be slid therein, a conical head on one end of each of said rods, a head having inclined surfaces on the other end of each of said rods, and cams slid on one of said plates and adapted to coact with said inclined surfaces whereby said conical heads are simultaneously forced into the split ends of the inner filing members, substantially as set forth.
